Plastiki

Created by David de Rothschild, Plastiki made international headlines in 2010 when it sailed 8,000 nautical miles across the Pacific Ocean from San Francisco to Sydney. The 60-foot catamaran, made of 12,500 2.5-liter plastic bottles and other biodegradable products, draws attention to the 73.9 million pounds of plastic waste that has been dumped into oceans.
